Rollins mentioned the series the Phillies have with the Oakland Athletics Sept. 19-21 as a target to return. That may no longer be the case.

Phillies manager Ryne Sandberg had much better news after Rollins was examined both Monday night and Tuesday.

"Jimmy has a mild hamstring string strain," explained Sandberg. "So he's listed as day-to-day. A little better than what we were thinking last night. ... We'll monitor him."

Sandberg wouldn't set a target because of the nature of hamstring injuries.

"They're tough to get behind you," said Sandberg. "You have to miss days to get back to where you want to be. We'll check him day-to-day."

The 35-year-old played in 138 games this season, hitting .242 with 17 home runs. He also leads the Phillies in runs scored (78) and walks (64).

Rollins had a 2015 option tied to plate appearances trigger earlier this season, however, his contract states the option only holds if he is not on the disabled list at the end of 2014. If he is, a mutually deemed upon doctor would have to declare him healthy for Opening Day next year.

With extra room because of expanded rosters, Rollins should avoid being placed on the disabled list making concerns about his 2015 option moot.
